📍 Geographic Location of Casablanca
Geographic Context and Coverage
Area code 5223 is a geographic National Destination Code (NDC) within the Moroccan numbering plan, allocated to the economic capital, Casablanca. Specifically, it serves the central and eastern districts of the Casablanca-Settat region, including the administrative arrondissements of Sidi Belyout, Maârif, and portions of Aïn Sebaâ. This code is assigned to fixed-line PSTN services operated by Maroc Telecom and other licensed fixed operators, and it follows the ITU-T E.164 standard.
Dialing Formats and Usage
When calling a 5223 number from within Morocco, subscribers must dial the trunk prefix 0 followed by the NDC and the subscriber number, resulting in the national format: 05223-XXXXX. For international callers, the country code +212 replaces the leading zero, yielding the international format: +212 5223-XXXXX. Note that the total number of digits after the country code is nine, consistent with the national numbering plan.
Local calls within the same geographic area may sometimes be dialed without the area code, depending on the operator's dialing plan. However, for clarity and to avoid misdialing, it is recommended to always use the full national format, especially when calling from mobile networks.
Overlay and Numbering Considerations
Casablanca has multiple geographic area codes (e.g., 522, 523, 528) to accommodate the high demand for fixed lines in the metropolis. These codes are not overlays in the strict sense; they are distinct NDCs serving different zones or exchanges. Therefore, callers must dial the correct area code to reach the intended party. Number portability is available in Morocco, allowing subscribers to retain their numbers when changing operators, but geographic numbers generally remain tied to the Casablanca region.
Caller Instructions
Domestic callers outside Casablanca should dial 05223-XXXXX. International callers should dial +212 5223-XXXXX (or the appropriate international prefix from their country, e.g., 011 from the US/Canada). Ensure you drop the leading zero when using the +212 country code. For example, a typical number might be +212 5223-12345.
This code is primarily used for fixed-line voice and fax services. VoIP services may also use geographic numbers, but they are not tied to a physical location. Always confirm the correct number with the recipient to avoid misrouting.
